Your zealous nature allows you to bring those who commit evil to justice.
Prerequisites
Wisdom 13, Planar Bloodline (Celestial).
Benefit
At the start of each day, you gain a number of points of zeal equal to your Wisdom bonus (minimum 1).
By spending a point of zeal as a free action, you may attempt to smite an evil creature as part of an attack with a melee weapon, granting you a bonus on the attack roll equal to your Wisdom bonus (minimum 1) and a bonus on the damage roll equal to the twice the number of Celestial Feats you possess. If you accidentally smite a creature that is not evil, the attack deals no damage, but the point of zeal is still used up for the day.
Special
If you possess levels in a class which grants zeal, you add the points gained by this feat to determine your total daily uses of zeal.
